Pfizer and BioNTech say data shows COVID vaccine is over 70% effective in young children, with cases now rising in just 7 states

Pfizer and its German partner BioNTech on Tuesday offered updated COVID vaccine data supporting efficacy in children ages 6 months to 4 years.

that updated analysis of 34 cases occurring at least seven days after a three-dose regimen showed a vaccine efficacy of 73.2% among children in that age group. Vaccine efficacy was consistently above 70% in both children 6 months to 23 months and children 2 to 4 years of age.

Sequencing of the cases confirmed that the majority were caused by omicron BA.2, suggesting broader protection across variants.

The US Food and Drug Administration licensed the vaccine for very young children on June 17 and it is currently under review by the European regulator.

“While these results confirm that three 3 [milligram] doses of our COVID-19 vaccine provide young children with a high level of protection at a time when the Omicron BA.2 strain was highly prevalent with a favorable safety profile, we are also developing an Omicron BA.4/BA.5 adapted bivalent vaccine in this age group to address these sublineages,” said Uğur Şahin, CEO and co-founder of BioNTech.

The news comes a day after Pfizer and BioNTech said they had formally completed an application asking the Food and Drug Administration (FDA) to clear their experimental bivalent COVID-19 booster for people older than 12 years.

The new shot equally targets the original strain of the virus and the BA.4 and BA.5 strains, the latter of which is now the dominant strain of the SARS-CoV-2 coronavirus in the US.

The news comes as known COVID cases in the US continue to decline, though the true count is likely to be higher given the number of people testing at home, where data is not collected.

Cases are rising in Georgia, Michigan, South Carolina, Tennessee, Mississippi, Missouri and Maine. They are falling in all other states.

The daily average of new cases stood at 92,602 this Monday, according to a New York Times tracker, down 16% from two weeks ago to the lowest level seen since mid-May. The daily average of hospitalizations fell 8% to 39,963, while the daily average of deaths fell 5% to 459.

• A study by Peking University and Tsinghua University in Beijing found that the incubation period for COVID has shortened with each new variant. The study was published in JAMA Network Open magazine on Monday. The researchers analyzed data from 141 studies and found that the incubation period decreased from an average of five days with the alpha strain to 3.43 days with omicron, which is now dominant worldwide. “The findings of this study suggest that SARS-CoV-2 has continuously evolved and mutated during the COVID-19 pandemic, producing variants with different enhanced transmission and virulence,” the authors wrote. “Identifying the incubation period of different variants is a key factor in determining the isolation period.”
